Shape pattern distribution of soil series for project of north Tikrit Agriculture in Salah_Aldeen Governorate

Abstract

A semi _ detailed soil survey project located north of Tikrit City was selected to determine soil series distribution patterns as well as their variability within the studied area . However a quantitative forms and shapes of representative mapping units were also measured . Tow strip transects perpendicular to each other were made and eleven soil series having 292 frequency were chosen for this study . result indicated that four bench-mark soil series are dominated in the study area . these series according to their area size and frequency , are : Hatra , 131FKW , Seneah , MW1, Shargat , 131FKE , and Kharag , 121FXW , Results indicated that area size of each series was correlated to number of its frequency .Shape index of map units related to the soil series studied that 93% of them were among the very simple , and medium complexity . Shargat 131FKE and Almangor 121FCW soil series showed the highest degree of similarity , However Shargat 131FKE also showed a highest dissimilarity with Sedaid 131FCE . It is also found that Hatra 131FKW was the most associated series with other series .
